Problems with Removing Personal Data
Importance of backups in personal data
Removing personal data from a database is a simple process, but eliminating that information from full backups could undermine the integrity of your data.
The problem is: what type of backup do you have? An incremental one? the differential backup? Or do you proceed with a full backup every time?
The right to be forgotten and backups present compliance problems. Backup software generally does not have the ability to interact with the data that it is backing up. If a database is included in a backup job, the backup software will back up that database without regard for the data within it.
Or maybe..the right to be forgotten should not be applied to backups.
